I regularly have customers that start the order process and then get scared off by the paypal gateway because they don't have a paypal account (even though my checkout gives directions on how to pay with a CC as a guest). Because of this, I'm loosing some potential business. I try to check my customer list and find any customers that have registered but didn't complete an order and give them a call but I am blind to what they are interested in as well as not getting an email notification that they were trying to purchase something.

How can I create an order/invoice when the user confirms the order, before they pay. Yet not email them said invoice until they actually pay for it?
